GAS-IGNITER.

Specification of Letters Patent.

lllatented Dee. 12, 191th.

Application filed September 23, 1912. Serial No. 721,762.

'0 all whom t may concern Be it known that l, REGINA KAI-1N, a citizenof the United States, residing at Milwaukee, county of Milwaukee, andState of Wisconsin, have invented new and useful Improvements inGas-Igniters, of which the following is a specification.

My invention relates to improvements in that class of gas igniters,which are adapted to be centrally located between a plurality of gasburners and from which radial jets of gas automatically ignited by apilot light are caused to flash out in close proximity to said burners,whereby gas may be simultaneously ignited in all or any one of saidburners at the pleasure of the operator.

My invention pertains more especially among other things, 1st, to thepeculiar construction of the igniter, and 2nd, to the construction andrelative arrangement of the gas controlling valve by which gas isadmitted to such igniter.

My invention is further explained by reference to the` accompanyingdrawings, in which- Figure 1 represents a plan view of the ignitercentrally located between several gas burners of the ordinaryconstruction. Fig. 2 is a vertical section of the igniter, the gascontrolling valve and a side view, partly in section, of the ductleading from the valve to the igniter, and Fig. 3 is a horizontalvsection, drawn on line of Fig. 2.

Like parts are identified by the same reference numerals throughout theseveral views.

1 represents the top of a gas stove of ordinary construction.

2 is a gas burner. The several burners 2 are connected with the main gassupply pipe 3 by the several branch ducts 4:, each of which is providedwith an ordinary gas controlling valve 5.

6 represents the igniter. rlhe igniter comprises two reversely curveddisks 7 and 8 which together form a chamber, both of which are supportedfrom the vertical tube 9. The lower disk 7 is provided with a centralaperture 10 and is supported from the sides of the tube 9, near itslower end, while the' disk 8 is preferably provided with a screwthreaded aperture 11, which has threaded bearings 12 on the top of thetube '9, whereby it is adapted to be adjusted upwardlyA and downwardlynearer to or farther,` from the opposing disk 7. The inversely curveddisks 7 and 8 are adjusted at a slight distance apart leaving an annularspace 13 for the free admission of air and for the escape of the jets offlame 14 by which the gas which in escaping from the igniter 6 isignited.

15 is a lock nut, by which the disk 8 is secured at any desired point ofadjustment nearer to or farther' from the disk 7.

The lower disk 7 is provided with a plurality of apertures 16 for theadmission of air, which is adapted to enter the space between the disks7 and 8- in a vertical course at right angles tothe jets of gas or flame14, whereby the air and gas are more thoroughly commingled together. Thevertical tube 9 is provided with a plurality of radial ports orapertures 17 for the escape of gas.

18 is a small pilot duct for supplying the pilot light 19 with gas,whereby as soon as gas is admitted to the vertical duct 9, it isignited, when the radial flame 14 is projected outwardly, whereby thegas which is escaping from any one or more of the burners 2 is instantlyignited. The igniter 6, comprising the several parts described, isconnected with the main gas duct 3 through the duct 20, valve chamber 29and supporting l. 21. The gas is admitted to the pilot light 19 from themain duct 3 through the branch ducts 22 and 23 and the small pilot duct18, and the amount of gas admitted to the duct 18 is regulated by thescrew 23', which has threaded bearings in the outer end of said branchduct 23.

The admission of gas to the duct 20 and thence to the igniter proper iscontrolled by the spherical ball valve 25, and said valve 25 is adaptedto be forced to its seat 26 by the spiral spring 27, said spiral springbeing interposed between said spherical ball valve 25 and the reducingsleeve 28, which reducing sleeve has threaded bearings in the walls ofthe valve chamber 29. The valve 25 is adapted to be instantaneouslythrown back from its seat by a forward pressure upon the push button 30,which push button is connected with the valve 25 through the valve stem31. The valve stem 31 has slidable bearings in the valve chamber 29.

32 is a packing nut of ordinary construction by which the escape of gasaround the valve stem 31 is prevented.

The burners 2 are provided with a plurality of apertures 33 for theescape of gas.

lt will now be understood that when any one or more of the gascontrolling valves 5 leading to the burners 2 have been opened, the i 5forward upon the push button 30, gas will be ,instantaneously ladmittedto the space between the disks 7 and 8, when it will be ignited by thepilot flame 19, whereby the jets of burning gas or flame 14 will fiashout in the four directions, as indicated in Figs. 1 and 3, whereby thegas which has previously been admitted to any one or more of the burners2 will, as stated, be instantaneously ignited. It will also beunderstood that the disks 7 and 8 may be adjusted nearer tol or fartherfrom each other, whereby the length of the radial jets 14 may beincreased or diminished to correspond with the distance of the burners 2from such igniter, and that the disk 8 may be rigidly locked at anydesired point of adjustment by turning down the lock nut 12 upon theupper side of said disk. It will also be understood that when the radialjets of flame 14 flash outwardly i from between the disks 7 and 8, thecurrents of' air induced by said jets are caused to rush inwardlybetween said disks, as indicated by the arrows 34 shown in Fig. 3,whereby a greater volume of air will be consumed and the volume of gasotherwise required to produce said jets will be proportionately reduced.

Having thus described my invention, what I claim as new, and desire tosecure by Leta ters Patent, is-

1. The combination with a main gas supply duct of a branch duct and avertical duct provided with a plurality of radial ports,

j means for controlling the admission of gas to said vertical duct andports, a pair of disks respectively supported from said vertical ductupon the respective sides of said ports, a pilot duct communicating fromsaid main gas supply duct and having its discharge end terminatingbetween said disks, means for controlling the admission of gas to saidpilot duct, one or more gas burners connected with said main gas supplyduct, and means for controlling the admission of gas to said burners.

2. The combination of a main gas supply duct and a vertical ductprovided with a plurality of radial ports,f1neans for controlling theadmission of gas to said vertical duct and ports, a pair of disksrespectively supported from said vertical duct upon the respective sidesof said ports, means for adjusting said disks nearer to or farther fromeach other,a pilot duct communicating from said main gas supply duct andhaving its discharge end terminating between said disks, means forcontrolling the admission of gas to said pilot duct, one or more gasburnersy connected with said main gas supply duct, and means forcontrolling the admission of gas to said burners.

In testimony whereof I affix my signature in the presence of twowitnesses.
